Professional opinions on a new prog

Hey guys, I'm hoping to wrap a couple of your brains around this problem I'm working on. Basically, without going into major details, I'm attempting to create a program where a user will type in his or her personal information. In the background, this set of data needs to be connected to an ID number, lets say 14. Then on another screen, a person will put in some misc info, possibly multiple sets of said misc info, that all need to be connected to the personal info that has the ID number of 14. Then they pull up a Crystal report where they can print out all their info that they have just entered. But then a month later, the same user, or a new user will use this program again, inserting the same personal info, but different misc data, which will all be assigned an ID number of 15, and print out the report for this set.
I've played around before, and I have problems automatically pulling the ID number from the personal info set to the misc data set, and then printing that active set in Crystal Reports. The best I could ever do, is manually put in the ID number of 14 in the multiple misc sets, have that connected to the personal ID info, and print it in Crystal Reports, but then Crystal Reports only acknowledges data with the ID number of 14, nothing else. I realize I've typed a ton, and hopefully I've made it clear as mud, but any help that I can get would be most appreciated.
